I'm running a vanilla 2.6.10 kernel patched with the acpi-2005-01-25 patch. When running the patched kernel, I noticed that my laptop makes a very strange and faint buzzing sound. I've determined that the buzzing sound is somewhat related to CPU and HD load. When the CPU load is heavy, or when the HD is busy, the buzzing stops. But when the system idles, the buzzing continues. I've also tried forcing the HD to go into suspension using hdparm, but the buzzing continues. Any hints or clues? If this problem hasn't been encountered before, I'd appreciate it if someone could give hints for how I can best go about isolating the problem. -Jing ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
